Dell iDRAC Service Module 5.3.0.0 User’s Guide
Isolation of OS to iDRAC Pass-through Independent feature
When iSM is unable to establish communication with iDRAC over the OS to iDRAC Pass-through interface, the iSM runs in the Limited Functionality mode and the core service remains functional. When iSM is running in the Limited Functionality mode, the following message with informational severity is logged on the host operating system:
ISM0057: The iDRAC Service Module is running with Limited Functionality Mode, hence some features are unavailable. Possible reasons are: 1) OS-to-BMC Passthrough setting in iDRAC is disabled 2) USBNIC interface on the host OS does not have a configured IP address.
On disabling the OS to iDRAC Pass-through interface from the iDRAC, iSM continues to run in the Limited Functionality mode. When iSM runs in the Limited Functionality mode, the iSM status in the iDRAC interface is displayed as Running (Limited functionality). If the OS to iDRAC Pass-through interface is enabled again, all feature states are updated according to the iSM configuration. During iDRAC reset, reboot, and racresetcfg, iSM switches to the Limited Functionality mode temporarily and restores back after the communication is reestablished. The feature is compatible with all operating systems that are supported on iSM 4.2.0.0 and later version.
